     * Enumeration of different approaches towards the interval and color scales in case of HeatMap layer.
     * Continuous - The distribution of the colors in the color scale is even based on the measure. This is good for the
     *   data sets with even distribution.
     * Quantiles - The distribution of the colors in the color scale is uneven based on the value. It is distributed evenly
     *   based on the measure for the lowest 10%, 10% to 20% and so on. Basically it categorizes measures based on to which
     *   quantile the measure belongs. This is good for data sets with uneven distribution.
